Changing the Zoom and pressing Spacebar, Backspace, and Ctrl+S is not
especially tricky, so I assume the difficulty is in finding Normal.dot?
Microsoft is definitely not helping with this by making it harder and harder
to find, especially since the path varies from one OS to another and can
also be customized by the user. Probably the easiest way to find it is just
to use Windows' own Find/Search feature. When it is found, so long as you
don't double-click on it but instead right-click and choose Open, you will
be okay.
I emphasize, however, that this procedure should not be necessary. Word
should remember the zoom in effect when you closed Word. If it doesn't, the
likelihood that this procedure will help diminishes with each version of
Word. It was quite dependable in Word 97 (for which that article was
written). For Word 2000 and 2002, it became more iffy, and for Word 2003, I
wouldn't even attempt it. To make Word 2003 "save" any settings reliably,
you need an AutoExec macro (Graham Mayor from time to time provides such in
these NGs), and I suspect that would be an even greater hurdle for your
users.
